Tonight’s (April 7) full moon is special because it occurs when the moon is close to perigee, the point in its orbit where it is closest to Earth.1,2 This event is called a perigee-syzygy by astronomers, but it is informally known as a supermoon. Because the moon is a little closer than normal, it will be a little larger in the sky than normal. However, this slight difference will not be readily apparent to observers. For those who can view the moon while safely practicing social distancing, tonight’s supermoon is a good excuse to do some backyard astronomy. It is also a reminder that the moon’s faithful regularity is due to the faithfulness of the One who created it.3
The full moon rises in the eastern sky around 7:00 pm. If you view the full moon when it is close to the horizon, it will appear quite large. However, this is not due to the supermoon per se. All full moons seem especially large near the horizon, even though the moon’s apparent size in the sky is the same near the horizon as it is high in the sky. It is an illusion that even today is not really understood.
Tonight’s supermoon is also called a “pink moon” in North America, but this is not because the moon appears pinkish in color. Although the moon appears orange-pink when it is near the horizon, the name “pink moon” refers to the fact that this supermoon coincides with the blooming of the moss pink wildflower.4
There is also a connection between Easter and the full moon. Easter is held the first Sunday after the first full moon that occurs on or after the spring equinox. The spring equinox this year was March 19, which occurred after March’s full moon on March 9. Thus, tonight’s full moon is the first full moon after the spring equinox, and Easter is celebrated the following Sunday. One unfortunate consequence of this traditional date for Easter is that it obscures the close connection between Good Friday, Passover, and Easter. In fact, Scripture says that Jesus is the Passover Lamb.5
For those who may be unable to view tonight’s supermoon, the next supermoon is May 7.
